Please review my letter, and let me know what I can fix any punctuation, run on sentences, grammar, etc. (took out all the names/personal info)

Dear,

I am writing to you today, to tell you about what I believe is important information about myself.
Not only will I be sharing insights on my life, but also hobbies and interests that I enjoy.

For starters, I love listening to music- I'm fond of 70-80’s rock, death metal, screamos, scene, and grunge. Some of my favorite bands include System Of A Down, Black Sabbath, Måneskin, P.H.F.Iron Maiden, and Metallica.

I also adore making jewelry, creating clothing designs, and dressing up. I like making kandi bracelets, faux facial piercings, and necklaces. When creating designs for clothing, I usually get inspired by Victorian clowns. Not too long ago, with some help, my grandmother and I made a full clown costume. I wanted to go for something more whimsical and child-like, so we used a pattern with cows, cats, spoons, dogs, and plates on it, in a baby blue color.

Something else I'm fond of is makeup, I love doing extravagant makeup looks, white face paint, colored contacts, etc. I do quite a bit of cosplay, mainly characters from creepypastas, which is one of my favorite fandoms. I love bloody, gory makeup, but in a beautiful way. Not necessarily scary, but not everyone's cup of tea.

Thank you for reading this somewhat long summary of the things in life that are important to me. I am enthusiastic about getting your feedback.

Best regards,

(will give brainliest to the best helper)
